All the symbols given above are defined earlier in the specification.
In the compounds or polymers according to the invention the anion A.crclbar. may be exchanged for other anions, e.g. with the aid of an ion exchanger, or by means of a reaction with salts or acids, optionally in several stages, e.g. by forming the hydroxide or the bicarbonate, or in accordance with German Published Specification No. 2,001,748 or 2,001,816.
The anion A.crclbar. is non-chromophoric and may be one which is conventional in basic dyestuff chemistry. The anion A.crclbar. is understood to include both organic and inorganic ions, e.g. halide, such as chloride or bromide, sulphate, bisulphate, methyl sulphate, aminosulphonate, perchlorate, benzenesulphonate, oxalate, maleinate, acetate, propionate, lactate, succinate, tartrate, malate, methanesulphonate or benzoate ions, or complex anions, such as those of zinc chloride double salts, and furthermore the anions of the following acids: boric acid, citric acid, glycolic acid, diglycolic acid or adipic acid, or addition products of orthoboric acid with polyalcohols, e.g. cis-polyols.
The new compounds or polymers according to the invention may be used as dyestuffs or they may be used in the form of aqueous, e.g. concentrated stable solutions or as granules in quaternised form and/or in the form of the corresponding salts of mineral acids or organic acids, for dyeing all types of fibre material, cellulose, cotton or leather, but especially paper or paper products, and also for bast fibres, such as hemp, flax, sisal, jute, coir or straw.
The dyestuffs may also be employed in the production of bulk-dyed, sized and unsized paper. They may be similarly employed for dyeing paper by dipping. Paper, leather and cellulose can be dyed in accordance with known methods.
In paper production, the dyestuffs according to the invention and their preparations do not colour the back water at all, or only slightly which is particularly advantageous for purification of the back water. The dyestuffs according to the invention are highly substantive, do not mottle when dyed on paper, and are substantially insensitive to pH. The dyeings on paper are notable for their good light fastness properties. After long-term exposure to light, the shade alters tone-in-tone. The dyed papers are wet-fast, not only to water, but also to milk, soap water, sodium chloride solutions, fruit juices and sweetened mineral water, and because of their good alcohol fastness, they are also resistant to alcoholic beverages; furthermore, when dyed on paper, they have a very stable shade.
The dyestuffs according to the invention may be used for dyeing, padding or printing polyacrylonitrile textiles, or polyamide or polyester textiles which are modified by anionic groups.
In the following Examples all parts and percentages are by weight and all temperatures are given in degrees Centigrade.
PAC (a) Preparation of the coupling component of formula ##STR56##11.3 g of ethyl cyanoacetate are added dropwise whilst cooling to a solution of 10.2 g of dimethylaminopropylamine in 200 ml of absolute ethanol, so that the temperature of the reaction solution remains constantly below 35°. The solution is stirred at 30°-35° until thin-layer chromatography indicates that formation of cyanoacetic acid dimethylaminopropylamide has ceased. Then, 1.7 g of sodium ethylate are added to the solution, which is boiled under reflux for 14 hours. The solvent is then removed under vacuum on a rotary evaporator and the remaining brown oil is taken up in 200 ml of dilute hydrochloric acid. The solution thus obtained can be used as such for dyestuff syntheses.
In the following Table I the composition of further coupling components is given. They may be produced analogously to the method described in Example 1 from suitable starting products and are of formula (Ia) for K12 and K13 or (Ib) for K1 to K11 and K14 and K15 ##STR57## where in formula Ib, R is ##STR58## for K1 to K11 and R is --OH for K14 to K15 :

13.8 g of o-nitroaniline are suspended in 200 ml of water, whilst adding 50 ml of 10N hydrochloric acid. 20 ml of a 5N sodium nitrite solution are added dropwise at 0°-5°, over the course of ca. 45 minutes, to the brown suspension. After the addition of the nitrite, unspent nitrous acid is decomposed with aminosulphonic acid. The diazonium salt solution is filtered by adding decolourising carbon, to produce a clear yellow solution. This solution is then added dropwise over 30 minutes at room temperature to a copper solution containing hydrochloric acid and containing 34.5 g of 4,6-diamino-1-(dimethylaminopropyl)-5-(3'-dimethylaminopropyl)-carbamoyl-1 ,2-dihydropyridin-2-one. During this addition, the pH is kept at between 2 and 3 by adding simultaneously a solution of caustic soda. When coupling has ended, the reaction mixture is rendered alkaline with ammonia solution, the dyestuff suspension is heated for a short time to 60° and allowed to cool to room temperature. After filtration, a dyestuff of the following formula ##STR61## is obtained.
From slightly acidic solutions, this dyestuff dyes polyacrylonitrile, cotton, leather and paper in yellow shades. Because of its good solubility, the dyestuff is especially suitable for the gel-dyeing of polyacrylonitrile.
In Table II further dyestuffs of the formula ##STR62## are given. They may be produced by an analogous method to that described in Example 1b from suitable starting products.

22.7 g of 4,4'-diaminobenzanilide are dissolved in 200 ml of water at 90° with 50 ml of 10N hydrochloric acid. 50 ml of 4N sodium nitrite solutions are added to the suspension which is obtained upon cooling to 0°-5°. After the addition of the nitrite, the unspent nitrous acid is broken down with aminosulphonic acid. The diazonium salt solution is filtered by adding decolourising carbon. The clear solution is added in drops in 30 minutes to a copper solution containing hydrochloric acid, and containing 69 g of 4,6-diamino-1-(dimethylaminopropyl)-5-(N-dimethylaminopropylcarbamoyl)-1,2 -dihydropyridin-2-one. During coupling, the pH value is kept at between 2 and 3 by adding simultaneously a solution of caustic soda. When coupling has ended, the reaction mixture is rendered alkaline with ammonia solution, the dyestuff suspension is heated for a short time to 60° and allowed to cool to room temperature. After filtration, a dyestuff of the formula ##STR68## is obtained. From slightly acidic solutions, it dyes polyacrylonitrile, cotton, leather and paper in reddish-yellow shades.
Table III gives the composition of further dyestuffs of the formula ##STR69## and these dyestuffs may be made by a method analogous to that of Example 26.

Dyeings on paper made from dyestuffs of Examples 2 to 26 and 28 to 30 are greenish-yellow to orange, from those of Examples 27 and 31 to 84 and from those of Examples 85 to 107 are yellow to yellowish-green.
The significances of X and E in the above Tables are as defined earlier in the specification.
70 Parts of chemically bleached sulphite cellulose (of pinewood) and 30 parts of chemically bleached sulphite cellulose (of birchwood) are ground in a Hollander in 2000 parts of water. 0.2 Parts of the dyestuff described in Example 26 are sprinkled into this pulp. After mixing for 20 minutes, paper is produced from this pulp. The absorbent paper obtained in this way is dyed reddish-yellow. The waste water is practically colourless.
0.5 Parts of the dyestuff of Example 26 are dissolved in 100 parts of hot water and cooled to room temperature. This solution is added to 10 parts of chemically bleached sulphite cellulose which have been ground in a Hollander with 2000 parts of water. After thorough mixing for 15 minutes, sizing takes place.
Paper which is produced from this matter has a reddish-yellow shade of average intensity, with good wet fastness properties.
An absorbent length of unsized paper is drawn through a dyestuff solution of the following composition at 40° to 50°. 0.5 Parts of the dyestuff of Example 26; 0.5 parts of starch and 99.0 parts of water. The excess dyestuff solution is squeezed out through two rollers. The dried length of paper is dyed reddish-yellow with good fastness.
2 Parts of the dyestuff according to Example 26 are dissolved at 40° in 4000 parts of softened water. 100 Parts of premoistened cotton fabric are entered into the bath, which is heated for 30 minutes to boiling temperature. The bath is kept at boiling temperature for 1 hour, and the water which evaporates is replaced from time to time. The dyeing is then removed from the liquor, rinsed with water and dried. The dyestuff is absorbed practically quantitatively on the fibres; the dye bath is practically colourless. A reddish-yellow dyeing is obtained with good light fastness and good wet fastness.
In Dyeing Examples A to D an appropriate amount of any one of dyestuffs of Examples 1 to 25 and 27 to 107 in liquid or granulate preparation form may be used instead of the amount of the dyestuff of Example 26 to produce good dyeings with good fastness properties.
